A comparative prospective study of platelet rich plasma vs. corticosteroid injection in plantar fasciitis

Abstract

Objective: To compare the relative effectiveness of intralesional Steroid versus Platelet- Rich Plasma injection among 80 patients in plantar fasciitis.Methods: A total number of 80 patients with plantar fasciitis were divided into 2 groups (Group A and B). Group A with 30 patients received intralesional Platelet Rich Plasma (PRP) and Group B received intralesional methyl prednisolone acetate injection. Pre and post intervention Visual Analogue Score (VAS), Foot and Ankle Ability Measure (FAAM) score and PF (plantar fascia) thickness for assessment of pain relief in two groups were recorded at 6 months.Results: The mean VAS scores for heel pain measured after 6 months of treatment were 1.460+0.6911in PRP group and 3.024+0.9572in steroid group. The decrease in mean VAS score in both the groups was statistically significant when compared with pre-treatment values (8.38+0.6820in PRP group and 8.44+0.6021in steroid group). The mean FAAM score measured after 6 months of treatment increased in both the groups (83.43±5.661in PRP group and 69.12±5.795 in steroid group)when compared with pre-treatment value (29.97±5.997in PRP group and 31.68±6.297 in steroid group)and it was statistically significant.There was 35.90% reduction in mean plantar fascia thickness in PRP group and 28.67% reduction in Steroid groupas compared to baseline values after 6 month of injection.Conclusion: Intralesional injection of both the PRP and steroid are effective and safe modalities of treatment for plantar fasciitis. Steroid is better for short term treatment of plantar fasciitis but in long term follow up platelet rich plasma therapy is better than steroid. Both the treatment methods have caused significant reduction in PF(Plantar fascia) thickness.
